Overview
The European Electrotechnical Standardisation Organisation for alarm systems together with many governmental organisations, test houses and equipment manufacturers has defined a common framework for surveillance video transmission in order to achieve interoperability between products. The purpose of the transmission system in a closed circuit television (CCTV) installation is to provide reliable transmission of video signals between the different types of CCTV equipment in security, safety and monitoring applications. Today CCTV surveillance systems reside in security networks using IT infrastructure, equipment and connections within the protected site itself. This European Standard defines general requirements on video transmission. A detailed specification on analog video transmission over different media including signal and performance requirements is already defined in prEN 50132-5-3. For the growing number of surveillance applications based on IP video transmission the requirements are defined in 2 standards. This standard covers in the following clauses the general requirements for video transmissions on performance, security and conformance to basic IP connectivity, based on available international standards. In areas where more detailed IP requirements are necessary additional specifications are given in order to reach compatibility. In this European Standard no detailed and special CCTV protocols are defined. In Part 2 of this European Standard, a detailed video IP protocol, messages and commands on top of the general connectivity and performance requirements of Part 1 are defined. Part 2 defines an IP protocol for full interoperability (for example, PTZ control, eventing, etcetera) of video transmission devices used in surveillance applications. The responsible committee is Subcommittee UK 713.1 "Gefahrenmelde- und Überwachungsanlagen" ("Alarm and surveillance systems") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
